(Solved) Problematic downgrade from Nougat to MM - Galaxy S6 Q&A, Help & Troubleshooting

Old:
Hey guys, I have SM-G920F 32 GB, which I kinda messed up. Here's the story: I was using custom 7.0 rom and decided to revert back to full stock 6.0. I flashed it with ODIN, everything was fine, until I saw storage field in settings was displaying 16 GB ? Tried smartswitch emergency recovery twice, both times freezed at 93%. Then I started searching for alternatives and I found a couple of another 6.0 multi-file roms, tried a couple of PIT-s, but still 16 GB. Any idea how can I get my other 16 GB back ? Thanks.
Edit: Flashed stock 7.0 and all my storage showed. I think the topic is completed.
New, 22.03.2017: I decided to downgrade to MM, I'm not happy with stock Nougat, but if I got only 16 GB of storage when returning MM last week, now I get red FAIL in odin while attempting to downgrade, tried a bunch of stock firmwares, different ODIN versions, everything. The error is always in the beginning, on sboot.img. Can someone help me to downgrade to MM ? Here's the info about my original MM with which I bought this phone:

And this is the result when I type my S/N in Smart Switch:
I hope these numbers help. As I mentioned, I tried everything I can, but no satisfying result...

I decided to edit and bump this topic, instead of creating new unnecessary one. Any help is appreciated.

flash to latest 6.0.1 with latest bootloader
i think bro you must flash to latest 6.0.1 with latest bootloader 5DQA3 instead of 4DPJG after flash by odin you must make full wipe (format +wipe cash)and i think this will solve your problem because you install nought that have newer bootloader and you downgrade to stock 6.0.1 with bootloader 4DPJG for that reason odin fail at sboot that will prevent you to downgrade old bootloader

odin flash failed (lollipop on n915F)

i have upgraded my note edge (n915F) via OTA to lollipop last night.
today i came to root it and odin failed.
i did the CF-Auto-Root-tblte-tbltexx-smn915f file and now i am screwed.
is there a recovery that will fix this?

Download and reflash your firmware from sammobile.com, then flash this through odin.

See post above, when flashing the CWM flash this SUperSU Update Zip to get root! It`s much more easier and safer....

No problem. Just flash cwm recovery with odin after you reboot into download mode and your phone will reboot fine
Sent from my SM-N915F using XDA Free mobile app
same happened to me and my phone stacked on Samsung logo ,, I downloaded and flushed stock rom from sammobile then I rooted with same post n. #
This happened because CF-Auto-Root-tblte-tbltexx-smn915f don't work with Lolipop

Downgrade and OTA update risks on osprey

Hi everyone. There are discussion spread on multiple posts about the problems we should have on downgrading from Marshmallow OTA updated. I created this thread in a attempt to centralize this.
Sounds like the previous Moto Gs (2013, 2014) users get a bricked phone when attempting to downgrade from OTA update to factory firmware and re-update it with OTA update again... This is related to the bootloader being modified by the OTA update. Because of this the recommendation for this devices is not to update their phones using OTA update if they want to downgrade someday.
Well, there are some successful reports from osprey (Moto G 2015) users doing this. Users like @drico_649 and @yea55 successful downgraded their phones.
I'm stuck on unlocked bootloader after a failed attempt to root Marshmallow. So, I need to downgrade my OTA updated to Marshmallow.
The obvious way is flash the factory firmware with fastboot and re-update to OTA Marshmallow but this is considered risky.
What are my alternatives?
Ok, I successfully flashed the factory firmware. Working normally!
But I got a unusual message:

It's portuguese:

That is this? I did not answer this.
So you can successfully downgrade the bootloader on your device? or did you skip gpt.bin and bootloader.img
The only thing people need to skip is gpt.bin

i swear the bootloader was thing you wernt meant to downgrade? and what happens if you do flash gpt.bin ?

If you flash gpt.bin, it will just fail, but it shouldn't cause anything. But for the bootloader, it will be downgraded with no problem at all.

No, you must be PURE stock to take an OTA update... Stock recovery, boot image, and system partition or it will failed. How you get there is up to you.

I am guessing there were 2 versions of your phone - you have to figure out (or guess) whether you have the newer one or the older one.
a) why do you have to get this update?
b) if it were mine and I had to guess I would choose the later one but you could well brick your phone. Permanently.
c) since you're twrp'ed and rooted, why not just flash something like LineageOS which is generally only 1 month behind on security fixes.
so.....let me help u......
the 2nd one is the new firmware image with july security patch........u must keep in mind that you can sucessfully flash an ota update until and unless u have a 1.unlocked bootloader or locked bootloader 2.stock rom 3. stock kernel......
okay.....i learnt from ur post u have unlocked bootloader.......so what u have to do is to go complete stock........for this....
1.go to @lost101 thread on factory firmware images
2.do what the thread tells
3.if u follow what the thread says.....when u have a stock kernel,stock rom,and unlocked bootloader
4.now update the otas
5.after update is complete,go again to fastboot mode
6.flash twrp with fastboot command
7.now root it with supersu or magisk.....
a)here is the beautifully written instruction.......https://forum.xda-developers.com/2015-moto-g/general/guide-fastboot-flashing-factory-t3187750
b)here is the firmware image......https://www.androidfilehost.com/?fid=529152257862686738
hope this helps......
@karimbo87 What is so special about this update? At 11MB it is a simple security patch, and those are not really important anyway.
+1
Thank you all, I updated it after flash stock firmware then i rooted it again

i tried that many times, it doesnt work.
Stock recovery wont help. Dload just take anything.
you may have flashed any custom ROM I guess? How about trying with B360 version and see the behavior via dload. If you need the files for it, there is one in my signature, 1st link. capture couple of files from it and proceed with dload.

Do you have stock recovery or TWRP now? You may need to flash srock recovery, stock boot, stock cust.img and stock vendor.img via fastboot.

Update failed "Failed to mount '/system' "

Hi,
I just tried to update my P20 from EML-L29 8.1.0.106(C432) to EML-L29 8.1.0.110(C432)-FULL.
My Bootloader is unlocked, the phone is rooted and TWPR is installed.
After the phone has downloaded the update and is rebooting into the recovery I get the following error:

Is this error normal, beacuse I unlocked the Bootloader of the device and the updater will just be blocked by Huawei or am I doing something wrong?
Is the another methode to update the device?
Thanks for your help

You need a zip prepared for twrp flash. I don't think there is any available
It might have changed since I did this the last time (a couple of years ago), but
When running stock firmware, and rooted, I never ever ever applied official updates.
It was doomed to fail. Then.
Today it might be different...?
- I recommend a Return To Stock, by flashing stock firmware. And yes, that will wipe all things on your device.
This is why one always uses backups such as Google Sync etc.
Best of luck m8
Peace ✌??
